I need all help and advice here. I'm in the process of rerouting a damaged HV wire that was installed thru the wall and pinned to the drywall. The wire had been cut but i can't pull it out because it is pinned to the stud in the drywall. What is the best thing I can do in this situation that will not violate the NEC code. Can I just disconnect this wire from both ends in such that it becomes a dead wire and leave it inside the wall? Is this ok? Also, the wire am trying to kill is also pinned to the stud with another live wire, will leaving a dead wire buried next to a live wire become a problem later or will it violate the NEC code? PLEASE HELP
